摘要: Abstract The S 1 -S 0 fluorescence excitation and dispersed spectra of jet-cooled 5-phenyltropolone were measured to investigate the effect torsional motion around bond joining phenyl group seven-membered ring in state. tunneling splitting origin band (18 cm −1 ) is only slightl smaller than that tr tropolone (18.9 ), while remarkably decreases splitting.
